Answer:
A- by questioning the messages in the media about sex
B- by relying on their friends for most of their information about sex
C- by discussing sex with close family members or a trusted adult
Step-by-step explanation:
The media can be very biased about sex and may show information that is not correct and that encourages prejudice not only about sex but about sexuality itself. It is not correct for a teenager to rely solely on the sex information shown in the media and always question whether the information is correct or not.
Ideally, the teenager should talk to a trusted adult and ask questions about sex. The problem is that sometimes talking to an adult can seem embarrassing, if so talking to friends can be a good alternative, but these friends should be people the teenager knows will give good advice and true information.
